Storyboard not loading properly in app extensions

Hi all,

I have an app that uses storyboards to power two extensions (a share extension and an iMessage app). Up until Xcode 15, these app extensions worked flawlessly. Now that my app is built with Xcode 15, these share extensions fail to load the main storyboards (I get a crash on my IBOutlets being nil).

Is there some setting in the new Xcode that I need to enable to make sure my storyboard is loaded properly? Or is this a bug that I should be submitting to the Feedback Assistant? I just want to inquire before I spend time building a reproducer project.
